Tutorial 9 facts!

Well, this semester is almost over...only a couple weeks left! So, here are my three facts about tutorial nine:

1). worm: A worm, which is a variation of a virus, is a self-replicating program that is commonly sent in e-mail attachments. I am not very familiar with viruses because I never had one on my computer. I believe it is important to learn about viruses, so that you know how to aid in the prevention.

2). necessity threats: I have never heard of something like this, but the book states that it occurs when an attacker disrupts normal computer processing or denies processing completely. The book has a good example of something like this; if an ATM transaction were to take 30 seconds instead of 2 seconds. This would be an intolerable slow speed and the bank would lose its customers.

3). white hat hacker vs. black hat hacker: Computer professionals use those two terms to distinguish between people who use their knowledge for good purposes and those who commit illegal acts. I thought this was very interesting.
